TodZZ whom it may 00mm:

Be itknown that 1, RALPH a citizen of the United States, residing inChester, Delaware County, Pe nnsylvania,

have invented certain Improvements in Machines forspllclng Feltsand'Fabrics, of.

. which the following is a specification.

'My invention is especially adapted for splicing felt which has to becoated by being passed through a coating or saturating .machine. Inthis'type of machine, a roll of felt is passed therethrough until theend I is reached, which end is secured to apiece of another roll,rendering-itunnecessary to thread the new roll through the machine, asit is drawn through by the rollv to which itis attached. The ends arepreferably detached afterthey have passed through the v 1 machine sothat each" roll canbe handled independently. I

The object; of

,vide a machine by which pieces of felt can .be secured together, in arapid manner. I 7 a --:-I-n the accompany drawings substantial and Fig.1 is a plan view ofmy improved machine: for splicing feltand otherfabrics;

Fig. 8 'is a detached perspective view of Referring to the drawings, 1is a frame.

supported on suitable legs 2. Carried by this frame aretwo beams 3spaced apartto form a channel i extending from one end of the machine tothe other. Mounted in the channel tie the needle carrier 5, shown G. JAonsoN,

through .the

V y; invention is to pro clearly in Fig. 5,]and-pjrojecting from thiscarrier arethe two lines of needles 6, preferably of thetype shown inFig. 5, said needles being shaped to penetrate the felt and having anotch 8. to receive the transverse threadwhich is passed through theloops when the needles, with their loops, are

projected through the fabric, as in 7.

At the end of each needleis a groove 7 for the other thread, or cord,whichis placed in the grooves, as shown clearly in Fig. 4.

a: isone sheet of felt and b is the other sheet of felt, which issecured to the sheet a.

0, 0, are the cords, which are formed into loops. d, d are the cordswhich pass loops and which complete the stitches. I

The needle carrier is raised. and lowered 1 by means of plungers, Fig.2. each of which is connected to one arm of a bell crank lever 10,pivoted at 11 to the frame 1. The other arm of each bell crank lever isconnected by .a rod 12 to a lever 13 pivoted at 14 to a bracket on oneof the legs 2. This lever 13 has a handle 15 by whichthe operatormoves'the lever.

. When it is wished to release the needle carrier and lowerit. the dogis raised clear of the plate :16, when the weight of the needle carrierwill cause it to drop to its normal. posltlon. I The needle carrier hasI On theframe is a plate and pivoted to the lever '13is a toothedprojections'lS at each end resting against abutments 19 on the frame.Directly above the needle carrier is a bar 20. This bar has a series-ofperforations corresponding with the needles so that theneedles, when theneedle carrier is raised, pass through thefabric and into theperforations of the bar. In the drawings, this bar is shown as made intwo parts, or sections. This bar is carried by the upper clamp members21 located at each side of the machine. EX- tending fromone clamp membertothe other are metal bars 22. '7 Clips 23 on the bar 20 engage thecross bars 22 and hold the bar 20 in'position so that it willmovevertically with the clamping members 21.

The bar 20 is "held against longitudinal movement by guides 24 mountedon brackee s 2:5 secured'to the frame 1. The beams 23 are permanentlysecured to the frame 1 and form thelower clamping members.

In order to raise and lower the upper clamp' nembers 4, two shezts 726are provided adapted to hearings on the beams 3. (in these eliaits areeccentrics 27 mounted in straps 28 connected by rods 29 to pins on theupper clamping members. 'Handlcs 31 a are provided tor turning theshatts 2 6 and their eccentricso that bythis means the .tvro pieces oi lQl't are firmly clamped to a ther While the needles are proj cted otarough the felt.

The cord 0 is pla ed in the groove 7 of the needles, as shown in Figs 4and 5, each needle being; threaded in the same direction and i suchamanner that when the needles are zrorced through the felt, a loop oi thecord 0 is carried through the felt with each needle. After the needlesare threaded, the.

parts of the machine are in the position sho vnin Fig. 3, the clamping 1embers bein;- raised.

"The felt, which is passed through the saturating niachinc, is stoppedWhen the end of illl piece of felt Z), the two felts having been thetwosections of teltare directly above the felt is in position above thesplicing de vice. The end of the felt a, as shorvn in Fig, 5, 1s lappedover the end of another cord cut each end, making line of stitches throuwet the Width of the fabric and the needles are Withdrawn. Thesestitches firmly splice the two ends of the felt together so that whenthe coating machine is set in motion one felt draws the elt o f theother i in through the space between the rolls Q or saturating machinelin tiie present instance, after the splice has passed through themachine, the felt is cut at this point and the roll previously coatinline with the toe loops of the" first cord so P after being drawnthrough, are tied to the cd is removed. from the machine and the newfelt forms another roll.

I claim:

l. The combination in a machine or splicing feltand other fabrics, oftwo clamps spaced apart for holding two overlapping pieces of felt; aneedle carrier having a series of needles, each needle having a slot inits end for the reception of a cord and also having a notch atthe sidefor the reception of a tying cord; means for causing; the neodles topuncture theftelt hold'l'ietiveen'the clamps, the said needles carryingwith them loops ot'one cord; and means for passing another cord throughthe notchesin the nee-.1

dles, and theloops so that, when theneedles are Withdrawn and the slackof the cord is taken up, thetwo piecesoffelt are firmly securedtogether.

2. The combination in a machine for splic ing'two pieces of felt,forother fabric, of

two clamps spaced apart; a needle carrier located between the clamps;two series of needles carried by the clampsya bar above theneedlecarrier and having perforations the needle bar and forcing the needlesthrough the felt, said needles being arranged to carry a loop of a cordthrough the pertorati in :lelt'to forma loop and means lor passing asecond cord get, when the needles are Withdrawn and e'cl'emps' arereleased, the two pieces" of material are firmly secured together.
